Application filed September 29, 1904. Serial No. 226,571.

To all whom it may concern;

Be it known that I, Asa ORLANDO W A'lTS, a subject of the King of GreatBritain, residing at Windsor Mills, county of Richmond, in the Provinceof Quebec, Canada, have invented certain new and useful Improvements inWeighing Apparatus; and I do hereby declare that the following is afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to new and useful improvements in weighingapparatus, designed especially for connection with railway cars, andadapted to weigh that portion of the car supported above the trucks andthe contents of the car, or, that portion of the car separately ifdesired, and consists in certain features of novelty in the constructionand arrangement thereof, all as hereinafter more fully described andspecifically pointed out in the claims.

The object of the invention is to provide an apparatus of the characterindicated, which may be permanently connected with a car, and which willregister the approximate weight of the contents of the car automaticallyas the car is being filled, and the exact weight of the contents of thecar by shifting a eight upon the balance beam, as hereinafter described.

Referring to the drawings, in which similar numerals of referenceindicate corresponding parts in all the views. Figure 1 is a fragmentaryview taken longitudinally of a car showing the middle portion thereof infull lines, with that portion of the car contiguous to the trucks shownin longitudinal section. Fig. 2 is a plan view of the under frame of thecar showing at one end, the right, the body bolster supported inposition, and at the left the body bolster removed. a transversesectional view taken approximately 011 line 3-3 of Fig. 2. Fig. 4 is anenlarged detail view showing the end of the balance beam which issupported below the car body, together with the indicating dial andpointer which is used to indicate the weight of the contents of the car.Fig. 5 is an enlarged fragmentary sectional View taken through the carfloor, showing one of the intermediate sills and showing the bodybolster and truck bolster 1n section with the balance beam held 1nposltion between ap- Fig. 3 is proximately V-shaped members carried bythe body bolster and truck bolster.

Referring to the parts, 6 indicates the center sills, which, as shown,extend from end sill 7 to end sill 7 at the opposite end.

8 are the intermediate sills, and 9 are the side sills, while 10indicates the sheathing commonly used in box car constructions.

11 are the truck bolsters, 12 are the body bolsters, and 13, 13" areapproximately V- shaped studs or extensions projecting re spectivelyupwardly from the truck bolsters at the sides thereof toward the middlepor tion of the car, and downwardly from the body bolsters at the sidesthereof adjacent to the end sill.

Resting upon the members 13 and below the members 13, are yoke arms 14,which converge between the center sills to levers 15, which meetintermediate the length of the car and approximately at the middlethereof, where said levers are held by a pintle 16, which is carried bythe yoke 17, best shown in Fig. 3.

The yoke 17 is connected by the pintle 18 with the transverselyextending bar 19, which is c rried at one end in the bifurcated lowerend of the hanger 20, which is connected with the floor of the car, orwith one of the sills thereof, as may be desired. This bar 19 extendsthence toward the opposite side of the car, and preferably terminatesbetween an intermediate sill and a side sill, as shown in the plan viewFig. 2, where a twisted link 21 is pivotally connected with said bar atone end and with the balance beam 22 at its opposite end.

The balance beam 212 is supported in a hanger .13, from which it extendspast the link 21, and as shown in Fig. 3, is connected with the coilspring 24, which. spring is wound upon the arbor 25, to which arborthere is attached the indicating pointer 26 cooperating with the scaleon the dial 27, which pointer and scale are adapted to registerapproximately the weight of the car body with its contents.

@ Carried on the balance beam 22, which j beam is serrated at.22, is abalance weight j 29, such as is commonly used on balance beams ofscales.

.lt Wlll be observed that the coil spring 24 passes downwardly from thearbor 25 around i the guide roller 30, so that as the beam 2 is liftedin a direction indicated by the arrow in Fig. 4, it will produce astress in said spring tending to contract the coils thereof, therebyactuating the arbor 25. Such actuation of thearbor shifts the pointer 26to indicate on its dial 27 the weight supported on levers In theemployment of my invention for the purpose of determining the weight ofthe cargo, or load, of a car, the balance weight 2 9 is adjusted toproper position on the beam 22 to shift the pointer 26 to zero on itsdial, under the combined action oi said balance weight 29 and the weightof the car transmitted to the levers 15. The car is then loaded, and theweight of such load will be accurately indicated by the position of thepointer 26 relative to its dial 27.

Cooperating with the balance beam 22 is a spirit level 31, which isconnected with said beam by means of the link 32, whereby the said levelserves as an indicating means to determine whether or not the balancebeam occupies a correct horizontal position. If the beam occupies anyother position it may be adjusted by properly shii ting the balanceweight 29 on its beam 22.

/Vhile I have shown in the accompanying drawings the preferred form ofmy invention, it will be understood that I do not limit myself to theprecise form shown, for many of the details may be changed inform orposition without a'il'ecting the operativeness or utility of myinvention, and I therefore reserve the right to make all suchmodifications as are included within the scope oi" the following claims,or oi mechanical equivalents to the structures set forth.

Having described my invention, what I claim and desire to secure byLetters Patent is 1. In a railway car, the combination oi a car body, atruck, hearings on said body and truck, levers supported between saidbearings, a pivotally supported rod connected to said levers, a balancebeam pivotally supported on the car body and connected to said rod, aspring connected to said balance beam, a pointer actuated by saidspring, and a graduated dial cooperating with said pointer,substantially as described.

2. In a railway car, a truck bolster, a body bolster, angular hearingson said members, levers supported between said. bearings and. extendingthence toward the middle portion of the car, ,a pivotally supportedtransversely extending rod connected with said levers, a balance beampivotally connected with the car body and connected intermediate itslength with said rod, a spring connected with said balance beam, apointer actuated by said spring, and a graduated dial over which saidpointer is adapted to travel.

In witness whereof I have hereunto set my hand in the presence of twowitneses.
